The L-rig Lose Fewer, Catch More Part 2 Text and photos: Jens Bursell Around half of the sea trout contacts on the Danish coast are lost on streamers. In 3/2011 Jens Bursell took a critical look at penetration and hook hold plus choice of hooks. In this issue he takes a look at tube flies and how new mountings, designed to maximize hook and gape exposure, depth of grip and penetration, can give you a higher landing rate. Small and better penetrating hooks does not necessarily equate to landing more fish. The hook test in 3/2011 illustrates the relative difference in penetration and strength of small/ thin vs large/thick hooks, but as such it says nothing about the actual landing rates of the specific hooks. The dimensions and pattern of the hook combined with the way you mount and fish it has a major impact on realizing the full potential of the superior penetration. How to convert the penetration potential of small hooks into higher landing rates is the subject of the next article in this series. Tubeflies one in avoiding losing fish. It is wise to change from a streamer to a tube fly enabling you to take advantage of small trebles or doubles. This results in a much lower percentage of lost fish, as long as the tube fly you use is relatively small and slim, leaving the hook points and gape well exposed. So why even think of fishing your tube fly in a different way? Even though many tube fly set-ups penetrate better and often give less leverage than the same size of fly tied on a big single hook, I believe there is still room for improvement - especially in terms of 1) getting a better exposure of the hook and maximizing the chance of getting a better grip in the first place and www.chasingsilvermagazine.com 71
therefore negated. In other words; you might end up losing more than you win. But when mounting the small treble off the central axis of the fly it is possible to use much smaller and sharper hooks, without compromising the exposure. The result of this is that you can now choose the most effective hook size as a choice, independent of the actual size, diameter and construction of the fly. This is not possible in the same way with conventional tubefly-set ups, where the hook is normally mounted close to the main body of the fly. Getting the grip I have found out, that a very easy way to get a good asymmetric exposure of the small hook is simply to mount the small treble loosely hinged in a bloodloop. The advantage you get by using this knot instead of the Rapala knot is that the blood-loop creates a 90 degree angle between the tippet The L-rig also works for big dryflies tied on tube. This P & T rainbow fell for a grasshopper foam fly fished with a size 16 treble. 2) taking advantage of the better exposure to use even much smaller hooks, which penetrate better. The perfect hook exposure My experience is that if you want to take full advantage of very small hooks, you must follow these rules: 1) The small hook must be mounted in such a way so as to ensure that points and gapes are completely exposed. With most flies, over 3-4 cm long and a thickness over 2-3 mm, this often implies that the off the central axis of the fly. Often, it is an advantage to mount the hook loosely dangling in a small fixed loop, as the hook will find a good hold this way. 2) The negative leverage-effect must be minimized or even better - eliminated. Small hooks on big flies Visual impact, search efficiency, or the need for a specific prey imitation, often dictates flies of a certain size or thickness. A good example, on the dominant shrimp species, as in the famous fly Pattegrisen. These flies are so big and thick that you will start losing fish if you mount a size 16-18 treble at the end of the tube. As clearly illustrated in the photo opposite page, the gape and points of the hook will be in the physical shadow of the body of the fly. When the points don t stick well out, the risk that they don t get a grip in the first place will increase. If too small a proportion of the gape is exposed, the hook will not grip as deeply as it could have, had the gape been fully exposed. The penetration a) The original Pattegrisen. b) Pattegrisen tied on a tube with a size 16 treble mounted with normal hookguard note the bad exposure. c) Pattegrisen fished with a L-rig and size 16 treble: All three gapes are 100% exposed, giving a deep grip in the flesh. The size 16 penetrates 2-3 times better than the streamerhook (a) (3/2011). a) b) c) and the loop, giving a much better exposure of the small treble. This is because it sits further away from the central axis of the fly; with help from gravity, the hook will always hang down just under/behind the fly. The best pricking and deepest grip you will achieve by maximizing the distance between the hook point and the axis of the fly (obviously, with the proviso that the hook must get well inside the mouth every time you get a bite). My experience is that the optimal distance between the point on the lower branch and main body of the fly (or lure) is 1-1,5 cm when the shank of the hook lies parallel to the hook is mounted asymmetrically Danish coast, is a fly imitating the advantage of the small hook is fly. The precise distance is adjusted 72 Chasing Silver Fly Fishing Magazine www.chasingsilvermagazine.com 73
A typical wakefly used for nightfishing after sea trout mounted on a L-rig with a simple blood-loop. x y When fishing the L-rig with a hookguard orientating the fly I prefer using stop knot of elastic powergum (y), when semifixing the hookguard. This is an elegant way to semifix the fly to the rig and an effective and visually delicate way to adjust the distance between hook and fly. The friction of the knot can be adjusted with the amount of turns on the knot. 4-5 turns Is normally sufficient for short soft casting and 6-8 turns is sufficient for more powerful casting. when fishing and optimized to the foraging pattern of the day. If you loose a fish (which rarely happens), make the loop a bit shorter and experiment until you have the right length. L-rig the simple way The simplest version is to tie the small treble into a blood-loop and then adjust the length of the loop when tightening the knot. The perfect length of the loop depends on the size and type of fly. The thicker the diameter of the fly, the more the loop must stand out from the central axis. This variant works well for sparsely dressed and/or small flies made out of stiff materials, where the hook will rebound if it swings round in the loop. If the hook tends to hang up on the fly, you can chose to simply dislocate the hook backwards a bit by pushing the power gum stop knot between the blood-loop and rear end of tube further up the tippet, as you do with traditional trailing hooks from tube flies. If the blood-loop is thinner than the diameter of the tube, you must put a transparent powergum-stop knot (y), a floatstop or the like between bloodloop and end of tube, so you avoid the knot being dragged into the tube, deforming the important angle of the knot. L-rig with stop knot When using more heavily dressed flies, it is an advantage to use a larger loop standing even further out from the fly and tie a small stop knot (x) made from clear 7 lbs elastic powergum (fx Gardner) on the loop, preventing the hook from swinging back in the loop and snagging on the fly. This is the variant of the L-rig I find best for most purposes with larger flies. Deeper grip better penetration and hook hold I believe getting a deeper grip on the jaw also means maximizing the chance that both point and barb will penetrate, because the deeper you go on the jaw the thicker is the penetrable layer. Or in other words the advantage of smaller hooks is not only a question of getting a better penetrating hook, but also using a hook where the distance from point to barb is shorter than the thickness of the penetrable layer. Its logical that your chance of getting a deep grip in the flesh or jaw is proportional to the free exposure of the hook point and hook gape. This is also one of the main advantages of The Hair Rig used by millions of carp anglers around the world as the most effective standard method to secure good hooking and hook holds. The underlying reason why sea trout on the open coast can be so difficult to hook is essentially the same as the reason why its difficult to hook the fish on The dangle when fly fishing in rivers: They are pricked on straight line. Our results with traditional mountings vs minute trebles mounted asymmetric, based on over 1600 sea trout contacts, clearly suggest that the problem of jaw hooking on straight line can be solved very effectively with set-ups such as the L-rig, or other related rigs such as the release-rig described in the next issue. 74 Chasing Silver Fly Fishing Magazine www.chasingsilvermagazine.com 75
How to tie a L-rig with stopknot 1 Thread the tippet through the eye and lay it parallel back along the tippet. 5 Open the middle turn with your right thumb nail. 2 Make the start of a 4-turn stop knot with a 10-12 cm piece of transparent 7 lbs powergum over the parallel tippet. 6 Push the hook through the middle turn. 3 Finish and tighten the stop knot, slide it down and create a small semi-fixed loop. 7 Moisten the knot - and adjust the length of the blood-loop when tightening the knot. 4 Continue tying the bloodloop by twisting the end of the tippetend five times round the tippet. 8 A fly with a L-rig stop-knot. Why not tail stingers instead of L-rig? Trailing hooks or stingers is another way of getting the hook out of the physical shadow of the main body of the fly, so it s possible to use smaller hooks. Quite a few do this on the coast; many in the hope of avoiding tail biters. But my experience is that in 90% of the situations where people loose fish they suspect to be tail biters, they are actually not lost because of tail bites but because of bad penetration from streamer hooks. Most often, the fish bite at the front/centre of the fly, and when doing this it often results in bad hooking, if there is only one hook situated at the very end of the tail. Another problem is dislocating the hook too far backwards on fx Pattegrisen makes it sink in an unnatural way. In order to make the fly sink in a horizontal position, the hook must be much closer to the centre of the fly, as with the L-rig. Lastly, trailing hooks produces more tangles than the L-rig. 76 Chasing Silver Fly Fishing Magazine www.chasingsilvermagazine.com 77
April s The L-rig Fav Lose Five Fewer, Catch more The L-rig Lose Fewer, April s Catch Fav more Five Displaced point of gravity When fishing asymmetric tubeflies such as fx shrimp imitations, mounting the small treble off the central axis of the fly ensures (with the help of gravity) the right orientation of the fly. This is not always possible with a normal symmetrical endmounting. With the L-rig you can orientate the fly correctly in the water, without needing to add extra weight in the lower part, causing the fly to sink faster than desired. a) Traditional tube-fly mounting. b) The L-rig. Advantages of the L-rig Making an effective tandem rig on very longtailed flies such as this sand eel imitation is easy with the L.-rig. Just leave the end of the tippet after finishing the bloodloop and mount a minute treble fx sz. 16-18 at the end of the tail The L-rig is a simple and good hook mount. In some situations such as sea trout fishing on the coast, where you let the fish run because it stays in the surface, you rarely find yourself in difficult hook and hold situations. Here the L-rig enables you to enhance the penetration in the region of 50-100% by dropping from a tube fly with a size 10-12 hook to a tube fly with L-rig and a size 16-18 without risking losing big fish. Using hooks of this size on asymmetric hook mountings, we have caught loads of sea trout up to 80 cm and have not experienced a single hook breaking or straightening out. Compared to streamers of the same size it is possible to enhance the penetration by as much as 100-200% with the L-rig. On tubeflies, where the tube runs symmetrically through the middle of the fly, all gapes will normally be 25-35% masked with the traditional hook guard mountings, but with a L-rig all the hook points are 100% exposed all the time, optimising the chance of hooking fish and obtaining a deep grip in the jaw at the same time. See detailed macrophotos of this at www.bursell. dk in the article Maximizing the gape exposure. Eliminating negative leverage The L-rig is not perfect as it gives almost the same low-moderate leverage effect as traditional tube fly mountings. In the next issue, I will take a look at how you can achieve, with a simple modification of tube flies and flies tied on hooks, an even higher landing ratio, than is possible to obtain with the L-rig. With this technique, The Release Fly, a combination of asymmetric hook-exposure and eliminated negative leverage-effect and will enable you to improve catch rates in the region of 50-200%, compared to what its possible to obtain with fx traditional streamers, and other large flies fished on a straight line. 78 Chasing Silver Fly Fishing Magazine www.chasingsilvermagazine.com 79
